I remember being asked by an extended family member on Facebook to identify a pretty white inflorescence in a shot I took while out walking the trails. We couldn't tell from the shot so I went back to take better pics, and my FB friends did help me figure it out. Here they are from two years ago. This was a bit of revival for me of my interest in identifying plants, but since then it has pretty much been the same process for me, "identify by asking FB friends" until I discovered iNaturalist this year.
